Question

I have the following snippet in one of my html pages :

<div class='inputboximage'>     <div class='value2'>     <input name='address1'  value='Somewhere' type='text' size='26' maxlength='40' />     <br />      </div> </div> 

My problem is that I need the inputboximage background to change when I click in the address1 text field and to revert to the original when it loses focus.

I have used the following :

  <script>   $(document).ready(function(){      $('input').focus(function () {          $(this.parentNode).css('background-image', 'url(images/curvedinputblue.gif)');     });      $('input').blur(function () {     $(this.parentNode).css('background-image', 'url(images/curvedinput.gif)');     });    });   </script> 

but instead of replacing the image, it seems to be adding a background image to the value2 div as you would expect. I can use parentNode.parentNode in this case, but there is also a chance that the inputboxImage node could be further up or down the parent tree.

Is there a way I can change this code so that it will navigate down the parent tree until it finds a div called inputboximage and replace the image there?

Also, if I have two different div classes, inputboximage and inputboximageLarge, is there a way to modify this function so that it will work with both, replacing the background image with a different image for each one?

Answer 1

I think using

$(this).parents('div.inputBoxImage').css(...) 

instead of $(this.parentNode) should work.

See the jQuery traversing documentation
